Account paid in full yet service suspended

I pay my Telkom mobile account via EFT every month as my pay date varies. The account is ALWAYS paid before the due date and is paid in full. Yet this month the "account has been locked". I have called 180 on 3 separate occasions over a 72 hour period to be repeatedly told "yes we have received the payment and will escalate the issue to be reconnected." Nothing, still not reconnected. This is impacting on my job as I have had no service for 3 days due to Telkom's ineptitude. I feel this is victimisation and once the contract ends in December 2017 I will be going to any other service provider. Telkom contracts do NOT even offer minutes anymore either. I dont need data I need minutes. I need this service to be reconnected as I have paid for it.
